To adapt the pistol grip size to different hands, Glock devised an interesting concept: the Gen 4 frame grip is smaller than the previous generations, and the back strap new shape allows mounting one of two additional interchangeable inserts, increasing the trigger distance. The fact that the frame is basically shorter longitudinally also causes the trigger housing to be accordingly sized, therefore incompatible with previous generation pistols. The Gen 4 also introduces a new and redesigned ambidextrous magazine release system, that is now extremely reliable; of course, backwards compatibility is also lost, and although Gen 4 magazines can be used in previous generation pistols, the opposite is impossible.
Most of the smaller parts remain unchanged: only for the Compact models G19, 23 and 32 , both the locking block and the spring loading the disassembly lever have been updated.
Notice that the slide and barrel finish are different, the Tenifer surface treatment has been replaced by a similar process that is faster and safer to apply and is reportedly much friendlier to the environment. The color of the metal surfaces of the Gen 4 are also different, being a lighter and somewhat duller grey. A close examination of the latest Gen 3 pistols shipped and all of the Gen 4 production reveals that a very through optimization of the design has been specifically carried out for this caliber.
With the new Dual Recoil Spring assembly, Glock managed to solve, or at least mitigate, a problem that affects all its. Matter of fact, the previous models G17 e G23 were essentially the same gun, but with a different barrel and slight modifications to the breech face of the slide to accommodate the larger cartridge. The recoil spring was the same, correctly dimensioned for 9mm energies and not for the much different. These translated into high residual energies transferred to the polymer frame, and an uncomfortable shooting experience.
The new Dual Recoil Spring assembly absorbs better the harsh initial spike and generally higher energies of the. The idea to use the same spring for both calibers 9mm and. And, that is exactly what happened, casting a doubt over the reliability of the new handguns, at least until Glock made the decision to introduce a specific recoil spring dimensioned for the 9mm caliber and offering a free replacement program for all the current owners of 9mm Gen 4 pistols. Even with this new recoil spring, the 9mm pistols could exhibit a softer and somewhat slower spent case extraction compared with the previous generation guns, and it was not uncommon to hear complaints in regards to ejection problems, such as stovepipes, cases not clearing the ejection port, and so on.
The cause appears to have been located in the new shapes and measurements of the Extractor, Ejector and the profile of the ejection window, all with subtle changes that added together have resulted in these problems. The new part carries the Part no. We mentioned that Glock manufactures and sells both Generation 3 and 4 handguns. Why keep both lines commercially available? We can only speculate on the reasons. First of all, Glock has many tenders, contracts and commercial agreements with Government Agencies that maybe even purchased large stocks of spare parts and may not accept a different and incompatible model as replacement.
If Glock manufactured only Gen 4 pistols, it would lose all sales in those States overnight. Third, and last, regards the public, like me and you: Gen 4 pistols, undeniably did not start on the right foot, and still today there are many customers feeling uncomfortable choosing the unknown path, therefore preferring a Gen 3 pistol… not realizing that the newest Gen 3 production is very similar to the Gen 4 guns.
We cannot give an unbiased answer, but there are at least two types of shooters who would benefit from the Gen4 new features: left-handers and die-hard fans of the. Frame: the dust cover features a wider channel to accommodate the larger Recoil Spring Assembly.
Slide: the front part of the slide features a larger hole to accommodate the bulkier guide rod. For those who still believe in a single recoil spring, conversion kits that allow the Gen 3 spring to be used in Gen 4 pistols are available. Trigger Housing: it has been redesigned to be compatible with the new and smaller frame; the connector engagement angle is also slightly different.

Additionally, a Glock's ejector is usually not a point of failure unless you are one of those lucky people able to run huge numbers of rounds. So, due to the cost of an entire trigger housing if it ain't broke don't fix it.
The one upgrade in the Glock 19 Gen 3 vs Gen 4 whirlwind is the lowly, but vital, magazine. Due to the ambidextrous mag release found on the Glock Gen 4, its magazines are notched on both sides.
If your Gen 4 mag release is still configured for a right-hand shooter, that means the mag release button is on the left side, then either magazine will work. The line of Glock handguns appeared on the market nearly four decades ago. Since then they have steadily grown stronger, firmly establishing their reputation as a durable, reliable weapon.
People generally lean either toward love or hate when it comes to a Glock. At its core, the Glock is a Spartan, all business handgun that is a pleasure to carry and shoot. The Gen 4 functions the same as the Gen 3 even when it comes to assembly and disassembly. So, why would you choose one over the other? Well, there are a variety of factors to consider for the Glock Gen 3 vs Gen 4 debate.
The first is the overall grip size and texture. The adjustable grip size would be a benefit if you had smaller hands or maybe average hands with short, stubby fingers.
This isn't a jab at anyone in particular. They make clothes and shoes in different sizes for different people and there's no shame in that. Why shouldn't our handguns be offered the same way? Perhaps you occasionally operate while wearing tactical gloves. That would be another reason to have the versatility of changing the size of the handgrips.
The Gen 4 has a new texture on its grip which many find just right for either bare-hands or gloves. You can get a solid purchase on the weapon without hurting bare skin. At the same time, the texture is not going to snag on gloves. There are many Glocks of all Generations available, so handle as many as you can to find the right one for you. You may love the new texture or hate it. However, you will never know until you try it.
If you happen to be a southpaw or like to practice firing with your off hand, then the ambidextrous mag release is definitely a factor. The size of the mag release button is nice as well. Yes, you could add oversize mag release button to an older Glock, but if you buy a Gen 4 they have already done it for you.
The dual recoil spring on the Gen 4 weighs in also. This system is nothing new to Glock as they have used it in their sub-compact pistols for years. On the Glock 19 Gen 4, one upgrade comes into play when you choose to go with a.
The heavier spring is designed specifically to not only manage recoil but to minimize abuse to the frame of the gun. This means that not only with the Gen 4 not only shoot easier, but it will last longer too.
Then there's the elephant in the room, price. Of course, the Gen 3 is going to be priced less than the Gen 4. However, when you factor in the perks that may apply to your situation just how much is that difference in price really?
I know, some people absolutely have to save every dollar they can, and that's okay. On the other hand, some people just have to have the latest thing on the market, and that's okay too. That's why they make chocolate and vanilla, everybody's different. The Glock 19 is arguably the perfect combination between a concealed carry and a standard service weapon. Its size is small enough to easily conceal, but it's still a handful of gun.
The magazine capacity coupled with the available calibers commands a bark that's as big as its bite. Oops, something went wrong. Please try again. Safety The traditional three-layer safety Glock safe fire system is still present.
Grip: Finger Grooves When looking at the forward edge of the grip you will notice the same finger grooves on both models. Reliability Also, you can't overlook the legendary Glock reliability. Availability of Aftermarket Parts And who doesn't like to change their guns up just a bit to fit their own style? What Was Upgraded in Gen4? Magazine Release Button Moving forward from the grips you will certainly see the larger mag release button, which is now been made ambidextrous.
Magazine When debating the Glock Gen 3 vs Gen 4 this is a valid point to consider even if you're not a lefty. Frame The next item to discuss in the Glock Gen 3 vs Gen 4 ordeal is the frame. Trigger Housing The trigger housing found in the Glock 19 Gen 4 was designed just a bit smaller than in the Glock 19 Generation 3. Magazine Release Button The next non-interchangeable upgrade is the Glock 19 Gen 4 magazine release button.
